Feasibility and Safety of Implementing Volumetric Arc Therapy (VMAT) for Pediatric Craniospinal Irradiation in a Low-Middle-Income Region: The Nigerian Experience.

Purpose: Volumetric modulated arc therapy (VMAT) is a relatively new treatment technique in sub-Saharan Africa. Although craniospinal irradiation (CSI) in the pediatric population has been practiced in Nigeria for many years, the use of VMAT to deliver this treatment is previously undocumented. We reviewed the first set of patients to undergo CSI at a cancer center in Nigeria, detailing the treatment technique, the progress experienced, dose statistics achieved, treatment toxicities, and cancer outcomes to date. Methods and Materials: This was a prospective case series of 5 children with histologically diagnosed cancers requiring CSI whose parents consented to the study. They were recruited at evaluation and followed through the process of their therapy. Toxicity was monitored at weekly review appointments using the Common Terminology Criteria for Adverse Events version 5.0. Follow-up of the children will continue in the long-term effects clinic. Results: Five patients with a median age of 6 were recruited. Diagnoses were intracranial germ cell tumor (n = 2), medulloblastoma (n = 1), pineoblastoma (n = 1), and ependymoma (n = 1). For all patients, a dose of 36.0 Gy in 1.8 Gy daily fractions was prescribed to the entire neuraxis. A subsequent boost of 18 Gy (n = 4) to 19.8 Gy (n = 1) in 10 daily fractions to the primary tumor bed (n = 2) and posterior fossa (n = 2) was delivered. Four patients had chemotherapy before, during, or after radiation therapy. No patient experienced grade 3 or greater toxicity. Conclusions: Our results indicate great progress has been made in the delivery of CSI in Nigeria, demonstrating tolerable acute side effects using VMAT. This series suggests the feasibility of implementing VMAT technology in low- or middle-income countries. Additional follow-up will be needed to determine whether survival rates and chronic toxicity rates are similar to those reported in the literature.

The Landscape of Pediatric Radiation Oncology in Nigeria.

Radiation therapy (RT) is an essential part of the multidisciplinary treatment of pediatric cancer. Over the past five decades, significant advances have been made in the delivery of RT, with better dose delivery to disease targets while minimizing exposure to nearby organs at risk. These advances have led to improved treatment outcomes, increased survival, and reduced treatment-related toxicities. Advanced treatment techniques, however, require significant investment in infrastructural and personnel resources. This review documents what is currently available regarding expertise and infrastructure for pediatric radiation oncology practice in Nigeria. It was performed to serve as a foundation for the creation and design of tailored solutions (initiatives and policies) to increase pediatric radiation availability, accessibility, and equity in Nigeria and ultimately improve pediatric cancer treatment outcomes in the region.

Surgical management of Aneurysmal Subarachnoid Haemorrhage in a resource-constrained region: A Nigerian regional experience.

Background: Aneurysmal Subarachnoid Haemorrhage (aSAH) is a vascular injury with significantly high mortality, especially when poorly managed. This study seeks to outline the experiences in setting up a neurovascular service in Lagos, Nigeria. Methods: A series of 45 patients were operated after aSAH over a period of 10 years. Patients consecutively were recruited following computed tomography angiography (CTA) diagnosis of aSAH. Clinical data were recorded on a predesigned form after obtaining informed consent; aSAH was classified using the WFNS classification, intraoperative findings were documented. Challenges in the management were analysed in a post-operative root cause analysis (RCA) review. Outcomes and factors responsible for the observed outcomes and actions taken were recorded. Results: Forty-five patients were operated after aSAH was confirmed; there were 29 females and 16 males. (M:F 1:1.8), the age ranged from 14 to 76 years (mean 49.1±13.58). All the aneurysms were on the anterior circle of Willis, mainly on Anterior Communicating Artery aneurysm (18/48).Thirty-eight patients (84.4%) survived and were discharged within an average of 10 days after surgery. Lower GCS at presentation was associated with poor prognosis (p = 0.026); however, data analysis demonstrated that other factors (financial issues, lack of appropriate instrumentation and equipment, experience of the surgeon) played a significant role in determining the outcome. Conclusions: Aneurysmal Subarachnoid Haemorrhage (aSAH) is a challenging pathology and its management may be further burdened in resource constrained countries, as shown by the data analysed in this study from Lagos, Nigeria. Specialized and well-funded Neurovascular centres are needed to overcome the challenges faced and to improve care for aSAH patients in Nigeria.

Patient-Reported Outcome Benefits for Children with Advanced Cancer and Parents: A Qualitative Study.

CONTEXT: Electronic patient-reported outcomes (e-PROs) in pediatric oncology may be useful to track patients' symptoms and quality of life (QoL). However, implementation in the clinical setting is limited and few studies have examined child and parent perspectives on e-PRO usage. OBJECTIVES: This brief report aims to explore child and parent perspectives on the benefits of using e-PROs to routinely report on symptoms and QoL. METHODS: We analyzed qualitative data embedded within the PediQUEST Response trial, a randomized controlled trial aimed at early palliative care integration for children with advanced cancer and their parents. Study dyads, made up of a child and their parent, completed weekly surveys assessing symptoms and QoL for 18 weeks, and were invited to participate in an audio-recorded exit interview to share study feedback. Interview transcripts were analyzed with a thematic analysis approach, with emergent themes centered on the benefits of e-PRO usage reported here. RESULTS: Of 154 total randomized participants, we collected 147 exit interviews representing 105 child participants. Interviewed children (n=47) and parents (n=104) were mostly White and non-Hispanic. Two predominant themes emerged regarding e-PRO benefits:1) raised reflection and awareness of self and others' experiences, and 2) increased communication and connection between parents and children or between study dyads and care teams through survey prompted discussion. CONCLUSION: Advanced pediatric cancer patients and their parents found benefit in completing routine e-PROs as they promoted greater reflection and awareness and increased communication. These results may inform further integration of e-PROs in routine pediatric oncology care.

Examining Cancer Patients' Perceptions of the Impact of COVID-19 on Teleoncology: Findings From 15 Nigerian Outpatient Cancer Clinics.

PURPOSE: To examine cancer patients' perspectives on the impact of COVID-19 on teleoncology in Nigeria. METHODS: Data from a multicenter survey conducted at 15 outpatient clinics to 1,097 patients with cancer from April and July 2020 were analyzed. The study outcome was telemedicine, defined as patients who reported their routine follow-up visits were converted to virtual visits because of COVID-19 (coded yes/no). Covariates included patient age, ethnicity, marital status, income, cancer treatment, service disruption, and cancer diagnosis/type. Stata/SE.v.17 (StataCorp, College Station, TX) was used to perform chi-square and logistic regression analyses. P values ≤ .05 were considered statistically significant. RESULTS: The majority of the 1,097 patients with cancer were female (65.7%) and age 55 years and older (35.0%). Because of COVID-19, 12.6% of patients' routine follow-ups were converted to virtual visits. More patients who canceled/postponed surgery (17.7% v 7.5%; P ≤ .001), radiotherapy (16.9% v 5.3%; P ≤ .001), and chemotherapy (22.8% v 8.5%; P ≤ .001), injection chemotherapy (20.6% v 8.7%; P ≤ .001) and those who reported being seen less by their doctor/nurse (60.3% v 11.4%; P ≤ .001) reported more follow-up conversions to virtual visits. In multivariate analyses, patients seen less by their doctors/nurses were 14.3 times more likely to have their routine follow-ups converted to virtual visits than those who did not (odds ratio, 14.33; 95% CI, 8.36 to 24.58). CONCLUSION: COVID-19 caused many patients with cancer in Nigeria to convert visits to a virtual format. These conversions were more common in patients whose surgery, radiotherapy, chemotherapy, and injection chemotherapy treatments were canceled or postponed. Our findings suggest how COVID-19 affects cancer treatment services and the importance of collecting teleoncological care data in Nigeria.

The path to becoming a clinical or radiation oncologist in Nigeria.

The number of cancer patients in Nigeria continues to rise; however, global advances in cancer research are making the provision of optimal care possible. Cancer management is globally agreed to be multidisciplinary, with patients now having the right to benefit from progress in systemic cancer therapy and radio-diagnosis by receiving treatment from adequately trained and highly skilled clinical and radiation oncologists. Radiation oncology is part of the three divisions that make up oncology - medical oncology, surgical oncology and radiation oncology. This discipline in recent times has been developed into Clinical Oncology and although both clinical oncologists and medical oncologists continue to deliver non-surgical cancer treatment, only clinical oncologists are qualified to deliver radiotherapy in the management of cancers. Though clinical oncologists continue to provide quality cancer workforce for the country's increasing number of cancer patients, much is still unknown about this discipline in Nigeria. It is hoped that inspiring radio-oncologists will take note of the information provided by this article as a guide. This paper chronicles the multifarious process involved in training to become a clinical and radiation-oncologist in Nigeria, plus the requirements, as well as pertinent information a budding physician seeking to advance in this highly specialised field requires.

Patient's Perspective on the Impact of COVID-19 on Cancer Treatment in Nigeria.

PURPOSE: Because of the global COVID-19 pandemic, health care organizations introduced guidelines for modifications to health and cancer medical care delivery to mitigate transmission and ensure quality health outcomes. To examine the extent and impact of these modifications on oncology service disruptions in Nigeria, we surveyed oncology patients across selected public and private cancer treatment centers. MATERIALS AND METHODS: Participating in the study were 15 tertiary cancer treatment centers across 12 Nigerian states. We recruited adult patients with cancer (18+ years) on active treatment to complete a self-administered survey on cancer care during COVID-19. We conducted descriptive and multivariate data analysis using Stata 16.1. RESULTS: Respondents were (n = 1,072), female (65.7%), ages 18-49 years (50.3%), and married (80.7%). The top two cancers were breast and prostate. Overall, 17.3% of respondents reported disruptions to cancer care, and more than half (51.0%) reported difficulties accessing care. Changes in chemotherapy regimens or route of administration were reported in 8.4% of respondents. Odds for any disruption were highest for older patients, western states, patients with prostate cancer, and patients with two or more flu symptoms. Odds for radiotherapy cancellation were highest for older patients, those with prostate cancer, and those with medium service perception. CONCLUSION: This study investigated COVID-19-influenced cancer treatment disruptions in Nigeria. Patients with cancer experienced significant disruptions to cancer care. Vulnerable patients are most likely to be negatively affected. Policies and strategies aimed at minimizing service disruptions while maintaining cancer patients' safety should be a priority for all health care institutions in the COVID-19 era.

Cancer pain control in a Nigerian oncology clinic: treating the disease and not the patient.

INTRODUCTION: inadequate pain control negatively impacts the quality of life of patients with cancer while potentially affecting the outcome. Proper pain evaluation and management are therefore considered an important treatment goal. This study assessed the prevalence of pain, the prescribing patterns, and the efficacy of pain control measures in cancer patients at the Radiation Oncology Unit of the Lagos University Teaching Hospital, Lagos. METHODS: this was a longitudinal study design recruiting adults attending outpatient clinics. Participants were assessed at initial contact and again following six weeks using the Universal Pain Assessment Tool developed by the UCLA Department of Anaesthesiology. RESULTS: among the patients reviewed, 34.0% (118 of 347) were at the clinic, referred for initial assessment following primary diagnosis. All respondents had solid tumours; the most common was breast cancer. The prevalence of pain at initial assessment was 85.9% (298 of 347), with over half of respondents, 74.5% (222 of 347) characterising their pain as moderate to severe. Over a quarter, 28.9% (100 of 347) of patients were not asked about their pain by attending physicians, and none of the patients had a pain assessment tool used during evaluation. In 14.4% (43 of 298) of patients, no intervention was received despite the presence of pain. At six weeks review, 31.5% (94 of 298) of patients had obtained no pain relief despite instituted measures. CONCLUSION: under-treatment of cancer pain remains a significant weak link in cancer care in (Low-to-middle-income country) LMICs like Nigeria, with a significant contributor being physician under-evaluation and under-treatment of pain. To ensure pain eradication, the treatment process must begin with a thorough evaluation of the patient's pain, an explicit pain control goal and regular reevaluation.

A review of breast cancer pathology reports in Nigeria.

BACKGROUND: Diagnosis and treatment of cancer rely heavily on imaging, histopathology and molecular information. Incomplete or missing tumour information can hinder the delivery of high-quality care in oncology practice, especially in resource-limited countries. To evaluate the completeness of histopathology reporting in a real-world setting and identify areas for future cancer care delivery research efforts, we retrospectively analysed reports from patients diagnosed with breast cancer who received care at a high-volume oncology department at a hospital in Lagos, Nigeria. METHODS: Demographic, institutional and histopathology characteristics were retrospectively obtained from 1,001 patient records from 2007 to 2016. Completeness was defined as reporting five tumour features (tumour histology, tumour grade, laterality, oestrogen receptor (ER) or progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2)) for biopsy specimens and seven tumour features (tumour size, tumour histology, tumour grade, laterality, ER/PR, HER2 and lymph node involvement) for surgical specimens. RESULTS: The mean age of patients was 48.6 ± 11.7 years with a predominantly female population (99.3%). A majority of pathologic reports were produced after 2011, and two-thirds of the reports originated from centres or labs within Lagos, Nigeria (67.7%). Most reports documented primary site (98.0%) and specimen type (85.0%) while other characteristics were less often recorded. This led to substantial variation in reporting between biopsy (13.4%) and surgical (6.1%) specimens for an overall low pathology report completeness <10%. CONCLUSION: The majority of patient records analysed lacked complete documentation of breast cancer histopathological characteristics commonly used in oncology practice. Our study highlights a need to identify and address the contributing factors for incomplete histopathological reporting in Nigeria and will guide future clinical programmatic developments.

Oncology Education in the Nigerian Medical Curriculum: A Cross-Sectional Review.

Background: The quality of a physician is arguably related to the depth and quality of medical education received. As cancer devastates the health and economy of developing countries like Nigeria, it becomes increasingly important for physicians in these countries to be equipped with basic knowledge and skill to adequately detect, diagnose, refer and manage common cancers. This study reviewed exposure to oncology training as a component of the medical school's curriculum in Nigeria from the trainee's perspective. Methodology: In a cross-sectional review of medical students and recent graduates of universities across Nigeria, data were collected using a predesigned tool. Results: Entries from 228 participants were recorded and analysed. The mean age of study participants was 25.4 ± 2.9 years; 53.1% were female. Respondents were primarily in government-owned medical schools. Over half (55.7%) reported none to minimal oncology exposure during their preclinical classes, 38.6% reported oncology as a distinct clinical rotation in their medical schools and only 44.3% spent time in at least one oncology unit during clinical rotations. The mean duration spent in oncology units was 3.4 weeks. Conclusion: Doubtless, Nigeria needs more oncology specialists but, it is just as important for even general practitioners to have basic oncology knowledge. This study shows slow exposure to oncology training for medical students, which has contributed to the lack of confidence in treating common cancers seen in Nigeria and low desire among medical students to specialize in oncology. As cancer incidence rises, the need for oncology knowledge in the general physician community is increasingly evident.

Factors Affecting Undergraduates' Participation in Medical Research in Lagos.

BACKGROUND: The current situation regarding the scope and contribution of undergraduate medical research to the health space in Nigeria is still largely unreported in formal literature. This study examined the knowledge, attitudes, and the perceived barriers faced by medical students in Lagos toward research. MATERIALS AND METHODS: A cross-sectional study design was conducted among all medical students in 200-600 levels of study at the College of Medicine, University of Lagos. With the aid of Self-administered questionnaires, we examined their knowledge of research and the analytical tools used in research, their attitudes and the perceived barriers to their participation in research. RESULTS: The data were obtained from 221 medical students, of whom 52.9% had prior involvement in research and 14.0% and 6.3% had presented or published their research, respectively. The overall knowledge of medical research was low (21.3%) and reported barriers included lack of funding for research' (79.6%), "lack of research and biostatistics curriculum" (76.0%), "inadequate training in research methodology" (74.7%), "insufficient time allocation to undergraduate research" (73.3%), "lack of professional supervisors and proper mentoring" (58.8%), and "lack of equipped laboratory facilities to conduct research" (77.8%). CONCLUSION: Our results highlight the need for more mentored supervision and training to improve their knowledge of the principles and techniques of clinical research to increase involvement.

Feasibility study of prospective audit, intervention and feedback as an antimicrobial stewardship strategy at the Lagos University Teaching Hospital.

BACKGROUND: Antimicrobial resistance, a global problem, is mostly a consequence of misuse or overuse of antimicrobials. This study sought to audit the compliance to hospital antimicrobial policy and determine the ability of medical students to carry out audits. METHODOLOGY: This was a retrospective study to determine compliance with departmental policies in the preceding 2 months in the Children's Emergency Room (ChER) using a checklist. The primary outcome was to determine the rational use of antibiotics. The secondary outcomes were to determine whether the de-escalation of antibiotic, change from intravenous to oral or change in prescriptions were performed in line with culture results based on the departmental policy. RESULTS: The records of 450 children who attended ChER of Lagos University Teaching Hospital in January and February 2018 were retrieved for this study, of which 279 (62.0%) were prescribed antimicrobials. A suspected or confirmed diagnosis of infection was made in 214 (76.6%) of the patients, significantly highest in the infant age group (P = 0.03). Cultures were taken from 94 patients (33.7%), and although not statistically significant, cultures were mostly taken from neonatal patients aged <28 days (20/49, 40.8%). Applying the criteria, compliance with departmental guidelines was found in 111 (39.8%) of the cases. CONCLUSION: We found that the use of antimicrobials was judged unnecessary in 17.2% of the patients seen in ChER. There was a poor practice of collecting samples for culture before prescribing antibiotics. Prospective audit and feedback is feasible and it can be done with medical students who will report their findings to consultants and other doctors knowledgeable in principles of antimicrobial therapy.

Choice of Future Location of Surgical Practice: A Survey of Surgical Trainees in Nigeria and Implications for Timely Access to Surgical Care.

BACKGROUND: There is inequity and maldistribution of the surgical workforce in Nigeria. Most specialists practice in second- and third-level hospitals often located in urban or semi-urban areas. A knowledge of the proposed choice of practice location of surgical trainees and the factors that influence the choice could provide insight into future surgical coverage and help in planning and policy-making. METHODS: This is a cross-sectional survey of surgical trainees attending the mandatory integrated revision and update course of the West African College of Surgeons. Anonymous structured questionnaires were self-administered to 200 trainees, of which 143 completed the questionnaires. RESULTS: The response rate was 71.5%. One hundred and six (74.1%) trainees preferred to work in a tertiary hospital on completion of training, 13 (9.1%) were in a Private Hospital, and 16 (11.2%) were undecided. Nearly all tertiary hospitals are in urban or semi-urban towns. The commonest factors influencing choice of practice location were proximity to family 19 (13.3%), proximity to hometown 11 (7.6%), availability of working facilities 10 (6.9%), income 7 (4.9%) and underserved areas 7 (4.9%). Of 122 (85.3%) trainees who agreed to work for some period each year (ranging from 1 week to 6 months) in a rural setting, 42 (29.3%) would do it without additional financial incentive. CONCLUSION: The choice of most surgical trainees not to work in a rural setting as specialists would exacerbate the ongoing surgical workforce maldistribution and inequity in Nigeria. However, the willingness of 85.3% to provide periodic rural surgical coverage could be leveraged in planning of initiatives to address the maldistribution.

Prevalence and Correlates of Unmet Supportive Needs of Nigerian Patients With Cancer.

PURPOSE: Diagnosis and treatment of cancer are associated with significant psychological distress, and patients face a broad range of challenges that create a vacuum of unmet needs felt by patients, such as a loss of personal control and frustration. The aim of the current study was to determine the magnitude, distribution, and correlates of unmet needs in Nigerian patients with cancer. PATIENTS AND METHODS: Using a descriptive cross-sectional approach, we assessed 205 patients with cancer who attended oncology outpatient clinics at the Lagos University Teaching Hospital. Eligible patients were administered the Supportive Care Needs Survey (SCNS) -Short Form 34 with a focus on five domains of need: psychological, health system and information, physical and daily living, patient care and support, and sexuality. RESULTS: Mean age was 47.4 ± 12.3 years and patients were predominantly female (96.6%). The most common diagnosis was breast cancer (92.2%), and mean duration since diagnosis was 20.9 ± 21.9 months for all patients. Mean SCNS score was 83.9 ± 24.8 and at least 46% of participants indicated unmet needs in 15 items of the SCNS. The most frequent unattended needs were related to the health information (53.4%), physical and daily living (49.4%), psychological (48.5%), sexuality, and patient care and support domains. None of the factors considered-age, sex marital status, family type, educational attainment, employment status, economic status, the presence of financial support, social support, and cancer type-was significantly predictive of unmet needs in these patients (P > .05). CONCLUSION: Nigerian patients with cancer experience considerable levels of unmet needs. These needs require urgent and long-term interventions to help patients achieve increased care satisfaction and a better quality of life.

The pattern of comorbidities in cancer patients in Lagos, South-Western Nigeria.

PURPOSE: Comorbidities have been indicated to influence cancer care and outcome, with strong associations between the presence of comorbidities and patient survival. The objective of this study is to determine the magnitude and pattern of comorbidities in Nigerian cancer populations, and demonstrate the use of comorbidity indices in predicting mortality/survival rates of cancer patients. METHODS: Using a retrospective study design, data were extracted from hospital reports of patients presenting for oncology care between January 2015 and December 2016 at two tertiary health facilities in Lagos, Nigeria. Patient comorbidities were ranked and weighted using the Charlson comorbidity index (CCI). RESULTS: The mean age for the 848 cancer patients identified was 53.9 ± 13.6 years, with 657 (77.5%) females and 191 (22.5%) males. Breast (50.1%), cervical (11.1%) and colorectal (6.3%) cancers occurred most frequently. Comorbidities were present in 228 (26.9%) patients, with the most common being hypertension (20.4%), diabetes (6.7%) and peptic ulcer disease (2.1%). Hypertension-augmented CCI scores were 0 (15.6%), 1-3 (62.1%), 4-6 (21.7%) and ≥7 (0.6%). The mean CCI scores of patients ≤50 years (0.8 ± 0.9) and ≥51 years (3.3 ± 1.2) were significantly different (p < 0.05). Patients with lower mean CCI scores were more likely to receive chemotherapy (2.2 ± 1.6 versus 2.5 ± 1.9; p < 0.05) and/or surgery (2.1 ± 1.5 versus 2.4 ± 1.7; p < 0.05). CONCLUSION: Comorbidities occur significantly in Nigerian cancer patients and influence the prognosis, treatment outcome and survival rates of these patients. There is a need to routinely evaluate cancer patients for comorbidities with the aim of instituting appropriate multidisciplinary management measures where necessary.

Prevalence and Pattern of Late-Stage Presentation in Women with Breast and Cervical Cancers in Lagos University Teaching Hospital, Nigeria.

BACKGROUND: Cervical and breast cancers are the most common cancers among women in developing countries contributing to high morbidity and mortality. Even though both these cancers have a better prognosis if caught early; however, studies conducted in Nigeria still show a large incidence of late tumor stage presentation. OBJECTIVES: This study aimed at identifying the patient and disease characteristics of women with breast and cervical cancers presenting at a tertiary medical facility in Nigeria, with emphasis on the prevalence of late-stage presentation and reasons for late-stage presentation. PATIENTS AND METHODS: This cross-sectional study recruited women at Lagos University Teaching Hospital (LUTH) with breast and cervical cancers from April to June 2016; an interviewer-based questionnaire was administered to 105 patients who seen to elicit information needed to achieve the set objectives. RESULTS: The mean age of patients was 51.09 (±11.70) years; majority had no known family history and no health insurance. Most cervical cancer patients were unaware of their human papillomavirus status. About 72.81% of all patients presented late, surprisingly 87.6% of patients presented in an appropriate health-care facility as place of the first contact, but still presented in LUTH at late stages of their disease mostly due to misdiagnosis. Reasons for late presentation included fear, misconceptions, misdiagnosis, ignorance, and prolonged investigation time. CONCLUSION: As late-stage presentation was associated with both poor health-seeking behavior and health system delays; interventions should not only include increased awareness for the early detection and diagnosis but also measures to ensure improvements in health service delivery to ensure timely diagnosis and the management of breast and cervical cancers.
